Replacing the key fob battery in your 2020 Jeep Cherokee should be a straightforward task. However, some users have encountered a peculiar issue where simply swapping the battery doesn’t immediately restore functionality. One Jeep owner experienced this firsthand, finding that multiple new batteries failed to work in their key fob. Interestingly, their old, weak battery would still operate the fob, suggesting a more complex problem than just a dead battery.
This individual discovered a unique workaround: after inserting a new battery that initially seemed unresponsive, they went to their 2020 Jeep Cherokee and used the fob-on-start-button method – the same procedure used when the key fob battery is completely dead. Following this action, all key fob functions returned to normal.
This experience leads to a suspicion that there might be an undocumented system in the 2020 Jeep Cherokee or its key fob that monitors battery levels. When a new battery is installed, this system might not immediately recognize the change in power, causing the fob to remain inactive. Even dealership staff, in this particular case, seemed unaware of this potential quirk. The dealer’s suggestions of a new fob, overpriced batteries, or reprogramming, all at the owner’s expense, proved unhelpful and costly.
It’s worth noting that older Chrysler key fobs reportedly had significantly longer battery life compared to this newer Jeep model. While features like remote start might contribute to quicker battery drain, the discrepancy raises questions about battery management in modern key fobs.
If you’re facing issues after a 2020 Jeep Cherokee Key Fob Battery Replacement, try the fob-on-start-button method. This simple step might be the unexpected solution to get your new battery working and avoid unnecessary dealer visits or expenses.
